vector control of of WRSM ( wound rotor synchronous motor

Hello MATLAB community.

i'm trying to simulate my wound rotor synchronous motor using vector control ( field oriented control ).

the thing is that it's rare to find out in the internet some application of this ..even articles..

so when i try to simulate with the inventer+SPWM the test work very well i find my speed reference goes to 120 rad/sec like here in thephoto.

now when i try to use my inventer+SPWM like this photo bellow:

it gives me a negative speed + the wrong reference speed while it should give me 120 like the first one.. any sugestions ?

here is my result:

Thanks.

From the diagram is difficult to spot the issue as everything is in a subsystem. I assume there is a sign mismatch somewhere. For a starting point about control and simulation of this type of motor check Simscape Electrical:
